Care Service Provider

Client:

A care service provider in Halstead who requires a clean, efficient and healthy air conditioning system for its facility to support staff & resident wellbeing.

The Challenge

The wall-mounted AC unit at this care service provider had been serviced annually, following general air conditioning maintenance recommendations. However at this time a specialised deep clean was needed.

Often weak or inconsistent airflow, nasty odours during operation, visible build-up of dirt and mould around fan and casing areas, as well as rising energy usage can be signs that more than routine maintenance is needed. In a care environment, these issues can quickly become a concern. Air quality, comfort and system reliability are all vital to maintaining a safe and healthy setting for residents and staff. 

What We Did?

We carried out a comprehensive deep clean of the customer’s standard wall-mounted AC unit.
While a typical service of this type usually takes around half an hour, the deep clean took approximately three and a half hours to complete due to the level of detail involved.

The process was designed to address areas that a normal service cannot reach, ensuring all internal and external components were thoroughly cleaned, sanitised and tested.

The deep clean process included:

• Full system preparation: The outer casing of the unit was removed and the surrounding wall and electrical components were protected using a protective shroud, ensuring the customer’s premises were safeguarded during the work.
• Cooling coil cleaning: A grime-dissolving fluid was applied to the cooling coil to loosen dirt and contaminants. The coil was then high-pressure cleaned, with the process repeated until the coil was completely clear of debris.
• Fan and casing cleaning: The same grime-dissolving treatment was applied to the fan and hard-to-reach internal areas of the casing. These parts were then flushed clean multiple times until all build-up was removed.
• Condensate system check: The drains and pumps were checked and cleaned to ensure free flow and prevent future blockages.
• System reassembly and testing: Once all components were thoroughly cleaned, the system was reassembled and a full functional test was carried out to confirm correct operation.
  

For comparison, a standard annual service would typically involve cleaning filters, spraying and flushing the cooling coil, checking condensate drains, sanitising the unit, applying an odour-busting freshener, cleaning the external coils and recording ‘Air Off Temperatures’ to confirm correct temperature ranges.

The deep clean extended this process by including complete disassembly, high-pressure cleaning and cleaning of internal components that cannot be reached during normal servicing.

The Result

After the deep clean, the AC system was restored to full performance.

• Strong, consistent airflow 
• Unpleasant odours were eliminated
• Cooling and heating performance improved
• The cleaning of coils and fans helped the system operate more effectively, supporting lower energy usage.
• The result was cleaner, fresher air throughout the area served by the unit, helping to maintain a healthy environment for both residents and staff.

When a Deep Clean Makes Sense?

For most wall-mounted AC systems, a standard service is recommended every 12 months to keep the system in good working order. However, depending on usage and environment, a deep clean may be needed once a year or every 3–5 years.

A deep clean should be considered when:

• Nasty odours are noticed during operation
• Dust or dirt is being blown out of the unit
• Mould or grime is visible on or around the casing and fan
• Airflow becomes weak or uneven
• Energy bills increase without a clear cause
• Unusual noises are heard from the system
• Residents or staff experience worsening allergy or respiratory symptoms

These are all signs that the system has built up internal contamination beyond what a standard service can resolve.

Advice & Next Steps

To maintain clean, efficient operation:

• Service regularly: Schedule a professional servicing at least once a year to prevent dirt and debris build-up.
• Plan deep cleans as needed: Schedule a deep clean when signs of build-up appear, or every few years depending on system use and environment.
• Monitor key indicators: Airflow strength, odours and changes in energy usage can all point to when a deeper clean may be required.
• Use professional technicians: Ensure engineers protect your premises, follow full deep-cleaning procedures and verify correct system performance through testing.

If you are in Halstead or the surrounding area and believe your air conditioning system may require attention, don’t wait until small issues become major problems.
